I vurcaii'iznn.

' Bie. it known that L FRANK'LIN W. KREMiiii, a citizen ofthe United States, residing at arlstadt, in the county of `Bergeny and State of New Jersey, have inventedl a new and useful Improvement-in 'Vulcanizera' of which i ythe' following isa specification. 'v

v My'invention relates to vulcanizing der 1 vices; and particularly to vulcanizers de- .m

signed forthe joining or splicing'of the ends of rubber tubing used in the making ofthe .finner tubes of automobile tires.v

The primary-object of my invention is to provide a v'ulcanizer ini-thev shape ofa 4casis finished. topermit the tire to be iemovedf Another object of my 'invention-islfto provide al vulcanizerin the shape' cfa/casing which can'be opened and closed in the manner just' mentioned; -and'which is adapte-d, 4when closed,4 to provide a .passage leading through the side thereoffto the inside of .i Athe same; this passage being intended to receive the iniiating tube for the tire; whereby the splicing of the ends of the inner `tube of the tire and the applicationof the valve patchcan be eifected at the same time. j A further ,object of my inventionis tol f providea casing'inclosing a space for receiving athermal agent; thel casing having an opening in its side and extending from' end to end ofthe casing; this opening Ii/.adapted to be closed by a hollow block or i ley'for'medto communicate with the space;

so that thethe'r'mal agent can beadmitted to the yinterior of the block also; thecoinvmunication between the space of the casing andthe interiorof the block being con- Y trolled by anyzsui-tablemeans.

i at' following description taken in `connection -'l`hel above and other objects and advantages of my invention 4will appear from the with the vaccompanying drawings; the saine characters` of reference being used tol indiv ycate the samepartson all views. .On saidI 'ii-tc drawings:

Fig 2 is a .vertical transverse sectioir vulcanizers shown in Fig. 9, illust-rating dimi Section 0f 'the' is a side elevation `of .this eX- v In the particular description Aof the draw-4 u ing, I use numeral l to indicate thecasiiig of my vulcanizer, which is supported upon feet 2. The f casing comprises 4a hollo-w cylinder 3 liaving'abore i extending' entirely through the same; and surrounding the '-cylinder; therewith, is a Ajac-ket'- 5, forming withthe.

cylinder?) an inclosed space v6. To 'this j 'spacej-I supply a thermal agent such as 4steam by means of a pipe or tube 7. This pipeniay be laidon thefloor or other sup# porting surface upon which restv the feet 2,

and preferably cast integral I ,and preferably communicateawith space 6 between the feet 2., I mayalso. provide a'4 suitable vent cock for the space 6 not-being shown on thedrawings.

Extending through the side of the casing,

; vent I and from end'to 'end-of the same,' is an opening 8 which, as shown on, the drawings,'

the removal of the tire 'casing when theends is preferably located lon .the upper sideory tcp ofthe casing. 'llhis opening'S permits ceve 'and be closed by a` key or iblock'94 i sides of the block or key 9 carry secureslto said lug a yoke 15.

'y or block 9 thus secured .that the tire tube may which ispreferably formed to 'be slipped into the opening 8 from either end thereof and to slide into closing position. The

' longitudinal ribs 10 which are received in grooves or guideways 11, theseA grooves or guideways being formedy in the sides 12 of the opening 8, so that the block is prevented from dropping into the bore 4. This bore of course is circular and the inner face of the block 9 is curved correspondingly, so fit snugly against the surface of the bore and the inside surface of the block.

The casing carries on its outside a pair of lugs 13, one of these lugs being located on each side of the opening 8. One lug 13 is perforated to receive a pivot bolt 14 which This yoke has a central bore 16 which is threaded to receive. a bolt 17 having a milled head 18. When this lug is turned down in the plosition shown -in Figs. 1 and 2, and the bolt 1T screwed into engagement with. the other lug 13, the casing will be forced against the sides of the key or .block 9 and this key tightly in the opening` 8.

he interior of ,the block 9 is hollow, providing an inclosed space 20 opening through the side of the block. I also form the jacket to inclose a valve chamber 21 leading through one side of the opening 8, at and being located in such position that it will register with the port '220 when the block 9 is in closing relation with respect to 'the opening 8. The chamber Q1 is separated from thespace (i by means of a web or partition having a port 2ll lwhich can be opened and closed by a valve 25. This valve Q5 is adjustable by means of a hand wheel 26 on lthe louter end of the stem 'ZT'of thisvalve ;gthis stembeing thrtaidedfand engaging the threaded bore of a sleeve or bushing 28, which screws into an opening leading into the chamber Q1 from the top of the casing 1; and by turning the hand wheel, the valve of course can be opened or closed at will. l

The casing of course is provided with webs or walls extending along the sides of the opening S and closing the space 6 in this way; and I prefer to provide the block or key 9 with a centrally located passage extending from the outer to the inner .face thereof; and this passage is formed by Joining the top and bottom.` of the key 9 by means of a circular web 30 and providing openings in the top or bottoni so that this passage will be entirely independent. and out of communication with the space 19.

The -utility of my invention will. now .be clear. inner Itube lof the tire are first joined in a 19 having a port The ends of the tubing to form the manner to be more fully described hereinafter, and then inserted into the bore l, through the opening 8, the key 9 inserted, and the bolt 1T is tightened to draw the sides of the opening 8 against the block 9. Steam is then admitted through the pipe 7 and into the space (i, and by opening the valve '25, the steam may also be admitted to the space 19 to effect the vulcanizing operation. After the splicing is finished, the valve '25 is first screwed shut and the screw 17 is next loosened and the yoke 15 raised.- The block. 9.can then be slipped out of the opening 8, steam being shut off by the closure of the'valve 25 at this time, and the tire can be lifted out of. the casing through the opening 8. V

-By providing the passage 29 through the key or block 9, I can fix the valve patch to the tire at the same time that the ends are i slipped through the opening 8 into the bore 1t and the block 9 caused to slide into position to close the opening 8. As a next step, the tire is forced against the surface of the bore 1, and after -the yoke is lowered and the bolt 1T screwed up, the valve can be opened and steam admitted. After the ends of the tire tube have been joined together securely vand to the valve patch, the steam can be sluit olf, yoke' 15 raised and the key or block 9 taken out to permit the removal of' the tire tube.

From the above description, it will be apparent that I have devised a very useful construction for in v purpose. The casing can be readily and quickly opened to permit the tire tube to be. properly disposed therein, and the operation of vulcanizingcan he effected in a thorough and expeditious manner. In some cases, I might even dispense with the block 9 by making the casing sufficiently resilient to enable the sides of the .opening 8 to be drawn together. ln such case. I would of course dispose the bore-29 in the top of the casing by for|nng r a semicircular groove in each side of the opening locating these selnicircular grooves opposite each other. so that they will form a passage through the casing into the oore l when the opening 8 is closed in the manner mentioned.

In Figs. (3 and 'i' I show a number of vul' ',lhereiii, a hollow filling block ment of the parts as fairly fall within the scope and spirit of m v invention.
